Yeah i don't get how they went from a reversible USB plug (you can already find those in the A format, that use a small lip with contact pads on both sides) to a 20(?) wire monstrosity carrying anything from several amps of 20V electricity to thunderbolt wrapped PCI traffic.

I'm being a bit snarky, but if you look at practically all the modern standards (HDMI, Thunderbolt, UCB-C), they are basically 2-TX and 2-RX pairs like Ethernet. The core problem with power is that you can't really pump laptop charge wattage down a USB cable without raising the voltage above 5V. Once you accept that, the engineering gets quite a bit more complicated and you have to negotiate so one side doesn't blow the other up.
